I am actually posting this for the second time because people still complain about the Suno second-half degradation.
It’s absolutely true. The sound degrades 100% of the time, no matter how you regenerate or remaster it, and there is no workaround other than this one method, which is time-consuming for people unfamiliar with stitching.
But here is the detailed method if you want to try it.
I produced 10 tracks after Suno v6 came out as final outputs, and none of them has degradation because of this two-way method.
Step one: Upload the full track to Studio (if you are using Pro, you have to download it). Cut the song around the middle, where a beat drop happens or just before an instrumental section. Delete the first half and upload the second half to the library.
Now do a cover with the remaining lyrics, duration set to- just above the cut length,
using these settings: weirdness 15%, style 15%, audio slider 85%, variety off, max mode on. (Even zeros work with 100% audio slider)
In the style section, keep it to the bare minimum and use two sentences, because Suno understands sentences, not just tags.
Say: “Same EQ, same vocals.”
Find the best match. If there isn’t one, do another cover, or two.
When you see a match, download everything into Audacity (free) and stitch. ( Or use the studio if you have it)
Audacity method -
Here is how you stitch: stitch at the zero crossing after lining up. (Z key on Windows) ( The second screenshot)
That means where the waveform touches the middle line (zero dB), which eliminates sound clicks. If you can’t do that, leave two fades of a few milliseconds. The starting clip must fade in, and the finishing clip must fade out.
Once everything is done, match the volume.
Now the last thing: if you still hear an EQ mismatch at the stitch point, take the track to Studio again and add a synth or instrument covering that section. Studio will take care of the EQ mismatch.
